Kate Middleton always dresses to impress -- even when she's playing field hockey with little kids.

Wearing a stunning blue-and-green tartan coatdress from Q by McQueen, the Duchess of Cambridge showed off her new hair and always-dazzling smile at St. Andrew's preparatory school in Berkshire, England, where she joined the students and teachers in celebrating St. Andrew's Day on Friday, Nov. 30. During the event, Middleton -- who attended St. Andrews from 1986 to 1995 -- even joined in a game of field hockey and gave a speech about her memories of the school.

"It is such a treat to be back here at St. Andrew's," she said in her remarks (via the Daily Mail). "I absolutely loved my time here. They were some of my happiest years...In fact, I enjoyed it so much that when I had to leave, I told my mother that I was going to come back to be a teacher."

That plan was derailed, of course, when the future Duchess met her Duke, England's Prince William, but Middleton, 30, is still involved with the school in other ways. As part of her visit to her alma mater, where she said she first "realized [her] love of sport," she helped christen the new athletic facilities by playing a bit of field hockey -- in heels!

Catherine, Duchess of Cambridge takes part in a day of activities and festivities to mark the occasion of St Andrew's Day at St Andrew's School on November 30, 2012 in Pangbourne, Berkshire, England. During her visit, the Duchess visited the Pre-Prep School for under-5s, unveiled a plaque to officially open a new artificial turf playing field and met members of the school's hockey team, which she played for during her time as a pupil at the school (1986-1995). The Duchess also toured the school privately and watched the school's Progressive Games which are traditional games played indoors by teachers and students on St. Andrew's Day.

"I hope that you all enjoy playing sport here as much as I used to and make the most of these incredible facilities," she told the children.

Incidentally, the Duchess has some incredible facilities of her own to enjoy. After spending the first year of their marriage in a quaint Welsh cottage, Middleton and her husband are planning to set up house in Apartment 1A of London's Kensington Palace, a four-story, 20-room flat undergoing a $1.5 million renovation.
